The mass treatment trial of pyrantel pamoate on Ascaris lumbricoides and Ancylostoma duodenale infections was carried out to school-children and inhabitants in rural areas in the central part of Korea. Pyrantel pamoate ("Combantrin") tablet (123 mg base) was administered as a single dose of 10. 0 mg per kg. body weight to a total of 4,198 Ascaris infected cases selected out of 4,436 (41. 6%) positives, who were screened from the total 10,660 collected stool specimens. Of these, only 3,169. cases were followed up after treatment to provide an analysis in this study. Incidentally 161 cases with concomittently infected hookworm were also subjected to assess the efficacy of pyrantel pamoate against A. duodenale. The egg negative conversion rate on A. lumbricoides was 95.3%, and on A. duodenale, 97.5% four weeks following treatment. In failed cases, the egg reduction rates on both of the infections were 97.6% and 97.3% respectively. No side effects and no problem in drug administration were demonstrated. It is concluded that this study confirms the high efficacy of pyrantel pamoate in the treatment of Ascaris lumbricoides and Ancylostoma duodenale infections and also proves the acceptability and safety of this drug in the mass treatment of ascariasis in a population with relatively high worm burden.

尋常性?瘡이 顔面에 甚한 女高生 40名을 double-blind試驗에 依하여 Vibramycin(Vibramyin 100mg을 1日 1回 經口的으로 投與)을 投與하여 다음의 結果를 얻었다. 1) Vibramycin 4週間 投與하였을 때 治癒率 은 80.0%이고 placebo를 投與時는 29.3%를 나타내었다. 그리고 治療效果는 投藥 3週에 顯著이 나타나기 始作하였다. 2) 投藥中止後 3週에는 治癒率이 Vibramycin 投藥群에서 減少를 보였으며 2名은 再發되었다. 3) 投藥 4週동안 治療效果가 不充分한 患者에게 3週間 더 延長하였을 때는 더욱 顯著한 效果를 볼 수 있었다. Forty high school girls with acne vulgaris were included in a double-blind trial to assess the tLapeu tic effect of Vibramycin (100 mg Vibramycin capsule, orally, once daily). The results, assessed clinically are as follows; 1. When Vibramycin was administered for 4 weeks, the cure rate showed 80. 0% and in the case of placebo, 29.3%, and the effectiveness was significantly appeared at 3 weeks of treatment. 2. In follow-up study, at 3 weeks after cessation of Vibramycin treatment, the cure rate decreased in Vibramycin group, and especially, in two girls, rashes like as inflammatory papules and pustules was reappeared. 3. When Vibramycin was administered another 3 weeks in addition, to those whom the effectiveness was insufficient in spite of 4 week-treatment, it had showed significantly beneficial effect.

A total of 63 subjects with multiple intestinal nematode infection: T. trichiura, A. lumbricoides, E. vermicularis and T. orientalis were treated with Oxantel/Pyrantel suspension and Mebendazole. The administration of Oxantel/Pyrantel suspension was 15mg/kg body weight in a single dose and Mebendazole was 600mg, divided by 100mg, twice daily for three consecutive days regardless of the body weight or ages. The results of present trials are summarized as follows: 1. The egg negative conversion rates for Oxantel/Pyrantel suspension were 100% in 20 cases of Ascariasis and in 3 cases of T. orientalis infection, and 92.3% in 26 cases of Enterobiasis. The egg reduction rate of T. trichiura was 84.8%. 2. The Mebendazole treated group showed the egg negative conversion rates of 100% in 27 cases of Ascariasis and one case of Trichostrongyliasis, 88.5% in 26 cases of Enterobiasis and 19.4% is 32 cases of Trichuriasis. The egg reduction rate of T. trichiura was 89.4%. 3. With the Oxantel/Pyrantel treated group, adult worms were found T. trichiura 1449 (average 45.3), A. lumbricoides 81 (av. 4.1) and E. vermicularis 249 (av. 9.6) worms. In Mebendazole treated group demonstrated the number of adult worms: 406(av. 13.1) of T. trichiura, 79 (av. 2.9) of A. lumbricoides and 134 (av. 5.2) of E. vermicularis, respectively. 4. Side effects of both Oxantel/Pyrantel and Mebendazole were few and mild.

The mass treatment trial with low dosage of pyrantel pamoate against Ascaris lumbricoides infection was conducted to school children in rural areas of Korea. A comparative trial in the use of piperazine salt, santonin-kainic acid complex in the treatment of ascariasis was also attempted to evaluate the efficacy of' pyrantel pamoate. A total of 804 Ascaris infected school children selected out of 822-positives, who were screened from the total 1, 699 collected specimens, were classified into 7 groups. One of the three kinds of anthelmintics, i.e., pyrantel pamoate, piperazine adipate and santonin-kainic acid complex was administered to each group according to the planned regimen. For the evaluation, the egg negative conversion rate(cure rate) and egg reduction rate were calculated 4 weeks after treatment on 623 follow-up cases with the obtained results from the stool examinations (Cellophane Thick Smear Method and Stoll's Egg Counting Technique). The results obtained were; 1. The egg negative conversion rate was the highest in pyrantel treated groups (Group 1, 2, 3), santonin-kainic acid complex treated group (Group 7) coming next, and the lowest in piperazine treated groups (Group 4, 5, 6). 2. The reduction rates were also obtained just as the same order of the above results. 3. Among the pyrantel pamoate treated groups, the low dosage groups (Group 2 8: 3) showed 90.6% and 85.7% of negative conversion rate, and 99. 2% and 98. 2% of reduction rate respectively, while 94.1% of negative conversion rate and 97.9% of reduction rate were obtained in the conventional dosage group (Group 1). 4. On the analysis of efficacy in the groups treated with piperazine adipate, the best results were. shown in 2 or 3 consecutively treated groups (Group 4 &.- 6) under the supervision of qualified doctors, and the worst was in the group treated with 2 consecutive administration by teachers without supervision (Group 5). 5. The side reactions were so negligible in all the trial groups that none of the treated cases complained about the known side effect of those anthelmintics. From the present study, it can be suggested that the pyrantel pamoate is the most effective among three drugs, and also be recommended to apply the low dosage schedule of pyrantel pamoate in the masstreatment of ascariasis to reduce the expense of masstreatment.

최근 고해상도 영상이 필요하게 되었으며, 저해상도 영상을 고해상도 영상으로 변환하는 딥러닝 기반의 초해상도 알고리즘에 대한 연구가 활발히 진행되고 있다. 그럼에도 불구하고 딥러닝 기반의 초해상도 알고리즘은 하드웨어의 한계로 인해 임베디드 시스템에서 실행시간이 느린 단점이 있다. 본 논문에서는 심층신경망 기반의 초해상도 알고리즘의 네트워크 구조를 제시하고 다양한 활성화 함수에 따른 화질 및 실행시간 성능을 분석한다. 실험 결과, 젯슨 나노보드의 다양한 활성화 함수 중 화질과 실행 시간의 관계에서 도출한 최적의 활성화 함수가 PReLU 함수임을 확인하였다.
